In the field of modern skin care and medical beauty, microneedling therapy has become a popular method of skin management. Microneedles can correct acne skin, and also make the originally dull skin shiny, promoting the smoothness and texture of the skin.

For beauty lovers, choosing the right microneedle tool is particularly important.

Suitable for deep acne pits, stretch marks, and obvious scar repair. Due to the deep penetration, it is usually recommended to operate by a professional to ensure safety.
2.0mm and above
It is mostly used for severe scars, stretch marks or deeper lines. It has great trauma and is not recommended for use at home. It needs to be done under the guidance of a doctor.
